SECURING DEVICE Cooper 0. Drury, Dallas, Tex. Application November 2,1946, Serial No. 707,431

This invention relates to new and useful im- 5 Claims. (01. 189-35)provements in securing devices, and more particularly to clips forsecurely aflixing insulating material and the like to stripsteel framingmembers.

In building construction, it is becoming more common'to utilize stripsteel framing members in the form ofan I-beam having a nailin grooveformed therein, of the type commonly known as .Stran-Steel. These framinmembers may .take the formofstuds, joists, ribs, purlins, trimmers andthe like, and other building materials can be nailed directly to theframing members, the nail being deformed and clinched as it is driveninto a nailing groove provided in the members. Due to the fact that theframing members are formed of steel, it has been diflicult to secureinsulating material and the like between the steel frame members in theusual manner.

It is, therefore, one object of this invention to provide means forsecurely affixing insulating material and the like between steel framingmembers.

A particular object of the invention is to provide resilient clip meansfor attaching the tabs of strips or bats of insulating materials tosteel frame members for securely maintaining such insulating materialsin proper insulating position.

A further object of the invention is to provide clip means of thecharacter described for releasably securing the insulating material tothe steel framing members, whereby alterations or adjustments in theinstallation may be made without damaging either the frame member or theinsulating material.

Still another object of the invention is to provide means for securelyafiixing insulating material and the like in place between steel framingmembers in such a manner that the installa tion does not interfere withthe normal use of such framing members.

An important object of the invention is to provide resilient clip meansfor securely affixing insulating material to steel framing members whichis arranged to hold the tabs on the insulating material againstdisplacement by so clipping the tabs to the framing member that forcetending to displace or free the tabs from the clip means increases thefrictional gripping of the clip means.

Additional objects and advantages of the invention will be readilyapparent from the reading of the following description of a device Gen-2 structed in accordance with the invention, and reference to theaccompanying drawings thereof, wherein:

Figure 1 is a fragmentary view, in elevation, of a section of a buildingwall illustrating the manner in which the securing means is aflixed tothe steel framing members.

Figure'Z is an enlarged transverse sectional view of the framing membershowing the clip in place thereon,

Figure 3 is a side elevation of the clip constructed in accordance withthe invention, and

Figure 4 is a plan view ofthe clip.

In the drawings, the numeral l0 desigates strip steel framing members ofthe type commonly known as Stran-Steel, which are formed of twosubstantially U-shaped or channel sections joined back to back toprovide the substantially I-shaped' framing members having alongitudinally extending nailing groove H between said sections. The webof the framing member is provided with one or more longitu dinallyextending convolutions Illa, whereby nails or the like driven into thegroove II will be deformed to conform to the shape of the convolutionsin the web and thus will be securely held in place in the groove. Theframing members are spaced apart in the customary manner to provide asupport for the walls or otherportions of a building, and wall board l2or other building material is secured to the framing members by means ofnails l3 or the like driven through the wall board and into the nailinggrooves H in said framing members. I

In building construction, it is frequently desirable that heatinsulating or sound reducing material be interposed between the outerlayers of wall board which are secured 'to'the framing members. In orderto properly support the insulating or sound reducing material'inposition between the framing members ill, some means must be providedfor securing such material to the framing members. The customaryinsulating material consists of an elongate strip or bat of wool-likematerial l4 enclosed in an envelope l5of suitable chemically treatedpaper or the like which is provided with=longitudinally extendingflange-like tabs l6 at opposite edges of one of the larger surfaces ofthe envelope. In the usual installation, these elongate marginal tabsare nailed or tacked to wood framing members to securely hold theinsulating material in place between the framing members.

In making. installation of the insulating material between the steelframing members, how- 3 ever, some other means must be provided forsecuring the tabs to the framing members.

A spring clip 20 formed from a single elongate piece of metal,perferably spring steel or the like, is adapted to slide over one halfof the flange of the I-shaped framing member In to releasably clamp thetab l6 of the insulating material to the framing member. The clip isformed by bendingan elongate strip ofspring metal upon itself to providean open loop 2 and an elongate outer leg 22 and a shorter inner arm 23.The end of the inner arm 23 is provided with a curved tip or finger 24which is turned outwardly away from the outer leg 22 of the clip tofacilitateentry of the flange of the framing member between the arm andthe leg of the clip. The inner arm is preferably bent towardthetouterleg 22 until the outer curved portion thereof is in closeproximity or contact with the outer arm, whereby the clip will securelyclamp any. material inserted between the inner endofthe'arm and the legTheextreme*outerend-of the'le'g 22 is provided with an inwardly turnedCa-lldh' Offt Hand-this 'ioo't' is' adapted toengage in the nailgroovellof the I-shapediraming member I 0 to prevent displacement of the =-c1ipfrom the flange of the framing member, whereby the clip and theinsulating material clamped thereby to the framing member are securelyheld in position on said framing member.

The length of theinner' arm'23 is such that it contacts the innersurface of the outer leg 22 at a point short of the foot 25 on said leg,whereby said am will terminate short ofthe web of the framingmemberandthe tab 16 on theinsu'lating material may be bent inwardly, in themanner illustrated' in Figure fl, to lie parallel to the inners'id'e'=of--the flangeof the framing member and "be clamped thereagainstby said arm when the clip member is slipped onto said framing member.

Since the clip is restrained against displacement iromthe framing memberby the engagement of the foot 25 within the nailing slot or 'g-roove lI'in thetrami-ngmember, it will be seen ward theweb of the framingmember and then around the finger 24 and outwardly away from the -web ofthe framing member. Thus, the clip isarranged tollold the tab on-theinsulating material against 'displacement'by so clipping :the tab to'the framing member that force tending .to *displace or "free thetab fromthe clip' increases the-frictionalgripping or the clip.

' "The clips are appliedat spaced intervals longi- 'tudinally of the"framing members, the spacing being such that the insulating materialwill be securely held improper insulating positionbut utiliaing aminimum of clips.

Gbv-iously, the clip may be "readily removed from engagement with theframing member by lifting thelioot ca tch 25irom within the nailinggroove :and sliding the clip outwardly 701T the flange; Thus, theinstallation may be altered or adjusted without damaging eithertheframing member or the insulating material, 'andthe :elip members mayberepeatedly used for clippmgor clamping the insulating material to theframing members.

Since the clips are formed of flat metal strips, they lie very closeagainst the flange of the framing member and do not materially interferewith the normal use of the framing members. Also, the clips will notprevent the entry of nails into the nailing groove in the framingmember.

Furthermore, the clips are resilient and may be readily installedwithout special machinery, without drilling additional holes in theframing members and without interfering with the normal use of suchframing members. Also, the insulating material is. securely andpositively held in proper insulatingposition between the framingmembers.

Theforegoing description oi the invention is explanatory'only, andchanges in the details of the construction illustrated may be made bythose skilled in the art, within the scope of the appended claims,without departing from the spirit of the invention.
